This invention relates to electric lightfixtures and especially tocandle sockets and the means for securing the same to a fixture bracket.y a i It. is an object of the invention to provide an approved andsimplemeans for securing a candle socket on a fixture arm which willfacilitate connection ofthe leads to the binding posts and which willalso facilitate assembling. It is also an object of the invention toprovide an improved hickey and means for securing thesame to theinsulating, body member of the candle socket whereby they may be easily.assembled or disconnecte-d. It is a further: object of the invention to.provide an improved construction and arrangement of the insulatingelements upon which the switch and contacts are mounted.

asegment 20 connected to a pull chain 21 whereby the same may beoscillated to rotate the switch contacts '22with a step by step actionthroughv suitable ratchet mechanism in any desired manner, and as thisforms no part of my present invention, I have not shown 'it in detail.Thefstationary switch contacts are indicated at 23 and 24, the contact23 being connected to the center lamp contact 17 by means of the support17 on 'which contact 17 is mounted, and the contact 24 being connectedwith the binding post 25 carried by a suitable plate 26 in a recess 27in one side of the bodymember 15. The support l'Z'is secured-to andbetween'the insulating blocks 15 and 15 adjacent. the upper ends thereofby screws 17 and 17 extending through, these blocks, screw 17 bei'n'gextended inwardly a sufficient distance if desired to form astop tolimitthe'backward movement of the segment 20.. On the opposite side of bodymember 15 is another recess 28 in which is mounted the otherbinding post29 carried by a plate 30 and which is connected to the screw shell lampcontact 16 through a U-shaped spacing element 16 and a screw 16 whichconnects plate 30 with element 16 There are two of these spacingelements the other being indicated at (16 .They also serve to secure theinsulating blocks 15 and l5 in spaced relation, being 7 connectedthereto by screws '16? and 16 passing through the blocks, These elements16' andiltiialso support the screw shell lamp 1 contact/16 to which itis secured by screws 16,-". V'lhe two recesses 27 and 28 extend at theirlower ends to the lower endtotbody I members 15 and 15" to-receive theleadwlres .11 as shown. in Figs. 1 and 3,.

Secured/Tm h fbOdy. members 5 1 T5" I at th "lower; end Y thereof is a tg late 31 having notches 32 ,Oni ltsnc. i

adaptedwhen' thefplat'e 1' A to t ends of the recesses 27 and 28 in thebody members. Secured upon the upper side of this plate, by any suitablemeans such as rivets 33, is means for securing this plate to the bodymembers. In the present in stance it comprises a plate 34 having twosets of upwardly extending arms 35 and 36 placed substantially in theform of a rectangle as shown in Fig. 5, the arms 35 be ing extended intothe space 37 between the body members for carrying the switch andsecured therein by suitable screws 38. The

arms 36 are provided with transversely extending screws 39, and theplate 34 is provided with elongated openings 40 in alignment with theouter surfaces of the arms 36 to receive upwardly extending spacedfingers 41 of the hickey. These fingers are provided with notches 40leading from their upper ends adapted to receive the body portions ofthe screws 39. There is a counter-sink at the closed ends of thesenotches as shown at 43 and the screws 39 are provided with taperedheadsto seat in these counter-sinks when the screws are tightened to thesecuring position. The hickey preferably comprises a collar 44internally threaded so that it may be threaded on the end of the fixturearm 10, and it is also provided with a flange 30 ing in the U-shapedplate 46, which includes 45 adapted to be extended through an openthefingers 41/ By rolling over the flange '45 as shown in Figs. 1 and 2,the plate 46 and the collar 44 are securely fastened together.

In assembling, the hickcy including the collar 44 and U-shaped member 46is threaded onto the end of the fixture arm 10, the ends of the leadwires having been brought out through this arm, the fingers 41 areinserted in the openings 40 and the screws 39 seated in the notches 42.These screws are :now tightened so that the tapered portion on the undersides of their heads seat in the counter-sinks 43 and securely fastenthe fingers of the hickey to the arms 36 and thus to the body member, aswhen the heads of the screws 39 are thus seated in the countersinks 43the arms 36 and fingers 41 cannot be separated. If it is desired toseparate the body member from the hickey all that is necessary is toloosenthe screws 36 to remove their heads from the counter-sinks 43,when the body member may be withdrawn from the hickey. It will. be notedthat as the arms 36 and screws 39 are located in the space between theinsulating body memhers 15 and 15 that they are above the top of cup'13, the height of which is fixed, and

sothese screws are accessible for easily connecting and disconnectingthe body members with and from the hickey after the hickey is mounted inposition on the fixture. Be-

fore placing the body member onthe hickey in assembling, the lead wires11 may be bent to opposite sides thereof, then after the body member issecured in position, it will be apparent their free ends may be easilysecured to the binding posts 2?) and 29. As the binding posts are inopen recesses in the lateral walls of the body member, it will beapparent that they are perfectly accessible. After the connections areproperly made the insulating sleeve 19 and shell 14 may be slid downover the body member from the upper end thereof. The pull chain 21extends through a guiding bushing 47 in the plate 31 and a similar guide48 in the can opy 12 and cup 13, projecting below the same where itterminates in the usual acorn 49 by which the switch may be operated.This construction and arrangement of the insulating body members forcarrying the switch mechanism, lamp contacts and binding posts, and alsothe means for securing the insulating body members to the fixture arm,provide a construction which is simple and strong, and one which may bemuch more easily assembled and connected up than those now generally inuse. At the same time they allow easy removal of the candle socket withits switch mechanism. for

inspection and repair.
